Great Kids’ Fitbit with Minimal Issues
Overall, this kids’ Fitbit has been a great purchase! The battery life is impressive — it easily lasts over a week, even with 24-hour wear. The sleep tracking option is a nice bonus, and it’s waterproof, which gives me peace of mind when my kid forgets to take it off for showers or swimming. The only downsides are that we had to buy a new charger after the original one stopped working within a few months, and the watch only syncs the correct time when it’s regularly connected to Bluetooth. Despite those minor annoyances, it’s a fun and motivating fitness tracker for kids. I’d still recommend it!

Absolute Trash Setup Process
**UPDATED REVIEW** Let me hopefully save you some headache. If you have an Android device, it seems that this process is a bit easier and the Fitbit app accepts a kid's Google account; however, if you only have iOS devices these are the issues, and the resolution: 1) The Ace 3 is designed for kids, but... 2) It REQUIRES a kids Google account, (and now that Google owns Fitbit, there are no non-Google accounts allowed to be created on Fitbit) 3) Anyone under 13 has to have a supervised Google account 4) Fitbit engineers overlooked this MAJOR detail and supervised accounts don't work on Fitbit right now 5) Changing an non-kid account to a kid account (via a birthdate change) doesn't work; Fitbit now says this type of account can't be used. 6) So, the only way it seems to make this work is to create a brand new child Google account FROM THE GOOGLE FAMILY DASHBOARD. If you don't create it from there, it won't work. I burned multiple Google accounts trying other ways. 6) I still think the setup process makes this worth one star at best. It's absurd that a product made for kids can't just be setup easily. It's also absurd that Fitbit requires all Google accounts, but hey DATA. 7) The dumb part is the Charge 6 we bought for our older child was so simple to set up. Everything worked the first time and it was done in 30 seconds. **ORIGINAL REVIEW** Would give zero stars if possible. Google, get your crap together. Setting up an Ace 3 on a supervised Google account doesn't work in the Fitbit app that you've now broken. And GUESS WHAT, a kid under 13 HAS TO HAVE A SUPERVISED GOOGLE ACCOUNT. Oh, I know, I'll just use a Google account with an older birthdate on it — NOPE, NOW THE FIBIT APP SAYS THAT'S NOT A KID ACCOUNT. Fix your junk and stop ruining Christmas for kids.

Nice active tracker for kids or adults looking for something basic
I like it for my son but... I had to lie about his age ( I had to put it in he was 12 instead of 13 on the app) because the app and watch are set up to only work on a parents account and once the child turns thirteen the app tries to force him to have his own account. The watch will not let it be set up on a private account for a thirteen year old. It was very inconvenient. It has held up well to being banged around and being in water. It was easy for my child to learn how to use. It does not break up the sleep tracking like their other Fitbits. It will only tell you how many hours he or she slept but it will not tell you how much of that was deep sleep, REM sleep or light sleep. I think it is a bit expensive for what it offers and the hoops you have to jump through if your child is 13 or almost 13 are no fun. I would only recommend if you can find it for sale like 50% off.

Great fitness tracker for kids
Got this for my child for a birthday gift and they loved it. It was easy to add them to my Fitbit account and it is fun to track their steps and sleep as well

Great for use as a Potty Watch!
We were looking for a way to help remind our child to use the bathroom throughout the day while at school. This fitbit - priced at $50 is a bit more expensive than other "potty watches" but you can set up to 8 timers throughout the day - varying by day (different schedule say M-W-F) with either a sounded alarm or silent vibration. This thing worked OUTSTANDING. Not only is it 100% waterproof- but the battery life of 1.5-2 weeks is also spectacular. Every $20-$30 option we could find for a potty watch seemed to fall short in quality or functionality. The wristband (minions) seems a little flimsy and expect it to fail within about 6 months- but otherwise if we can get 1 good solid year out of this device I will call it a win. My child also really likes the step count, and I find the sleep tracking to be extremely interesting and insightful! All in all a very good well made product for a child's entry fitbit as well use for steps, sleep tracking, and a potty watch reminder. I do recommend!

Decent upgrades to the best kid’s tracker out there!
*April 2022 update at the end* We’ve had this Fitbit Ace 3 since launch, and I’d like to point out a few of the upgrades when compared to the Fitbit Ace 2: - More rounded / Curved shape, seems like it would feel more comfortable to wear. The part to tuck in the strap is also better, strap doesn’t come out as often if your kid had that issue - Better screen - the animations and display look better - Longer battery life. It is now 8 days instead of 6, and the battery noticeably lasts much longer - New animated faces (a few), with apparently Minion licensed content and straps coming soon - No more one button on the left. Both left and right side have these two touch sensors which can be used for going back to the menu or activating the water lock - Waterproofing has been improved to a depth of 50m, but if your kid is going for a swim, they’ll have to turn on the water lock (long press of both sensors, and then double tap screen when it asks you to) - Still connects seamlessly with the Fitbit app and kids view mode etc. - BIGGEST UPGRADE: Fitbit has since the last 2-3 years moved to bad charging connectors in my opinion, the old Alta 2 ones were the best. The Ace 2 and Inspire use magnetic chargers made of plastic but they don’t hold well. With the Ace 3, they’ve added two clips that hold the charger in place. Not sure if other new fitbit chargers have this, but this is a big upgrade from the old Ace 2 charger which was not easy to hold in place All in all, neat upgrades to the best kids tracker out there, at the same price point as before! July 2021 update: as promised, Fitbit has updated the app to include new Minion animated faces! Kid loves it, thanks! :) April 2022 update: alright guys, the Fitbit Ace 3 that we have is going strong. Through sports, getting wet, and the daily wear and tear of a 6 year old. But CHECK THIS.. the battery life is just INCREDIBLE. This Ace 3 holds charge for 3-4 weeks easily. Easily. I’m curious to hear other peoples experience as we have a day one device, but I’m just blown away. They said the battery life was upgraded to 8 days, but going almost a month without charge is just amazing. Well done, Fitbit. Well done.
